Description of Components
Table 1: Humidifier Components
Component Function of Component
Actuator Opens and closes the CV valve in proportion to demand for steam.
Auxiliary Drain
Outlet Drains water from tank in case of pump failure.
Base Provides an integrated floor support for the humidifier.
Clean Out Port Provides access to clean scale from the tank and heat exchanger.
Condensate Drain Drains condensate formed from boiler steam in the heat exchanger(s)
Control Terminal
Strip Terminal strip for connecting external controls and blower pack to
humidifier.
CV Valve Controls the amount of steam allowed into the heat exchanger which in
turn controls the output of the humidifier.
Display and Keypad User interface for configuring the humidifier.
Drain Outlet
Drain port used for draining water from the humidifier tank.
Drain Pump Drains water from humidifier.
Driver Board Provides input and output connections to humidifier components.
Fill Box Provides an air gap for backflow prevention.
Fill Valve Controls flow of water into humidifier.
Float Chamber Measures water level in the humidifier tank.
Gasket Seals heat exchanger face plate and clean out port cover to tank.
Heat Exchanger(s) Exchanges energy from boiler steam to the tank water to produce steam
for humidification. The faceplate mounts the heat exchanger to the tank.
High Voltage
Terminal Block Primary power connection from remote disconnect to humidifier.
Manual Drain Switch Manually activates pump to drain water from the tank.
Mixing Box
Blends hot tank water with cool fill water to provide drain water cooling.
On/Off Switch Turns power On/Off to humidifier controller. Note: Turn off humidifier
disconnect to shut off primary power to the humidifier.
P Trap Prevents steam from flowing out the drain outlet.
Remote Relay
Board Provides a terminal strip to dry contacts which open/close to indicate
the humidifier is on, humidifying, needs service, or is in a fault condition.
Steam Inlet Connection for boiler steam, it is connected to the heat exchangers.
Steam Outlet Connect to steam line with steam hose.
Steam Trap Drains condensate from the heat exchanger without letting boiler steam
escape to drain.
Tank Holds the water used to generate clean steam for humidification.
Total Controller Controls all functions of the humidifier’s operation and provides user
interface for configuration of the humidifier.
Transformer Steps primary voltage down to 24 VAC for the controller and internal
components such as the fill valve and drain valve.
Vacum Break Prevents a siphon from occurring when the drain pump is stopped.
Wye Strainer Protects CV valve and other system components from dirt and rust in the
piping system.
